It is one of the objects of this invention to -provide a windowv screenvthat is collapsible in,4

--lar shape.

the accompanying drawings, a certain'preferred embodiment of myinvention. AFigure 1 is a front elevation showing a screen made inaccordance with the terms of this invention, mounted on a conventionalwindow A frame.

. Referring now to Figure 1. .a screenlll made in accordance with myinvention comprises four sections of angular strip framing II adapted tobe'mounted around a window frame I2, and suitably provided withprojecting .hooks I3 over which conventional wire or plastic screeningI4 may be stretched. y t .As `seen in Figure 2, the strip framing II maybe conveniently mounted o n the window frame vI2 by means of ordinarywood screws I6, I8,

adapted to be inserted through suitable openings formed therefor inabase plate member I 1, which is integrally formed- With a verticallyextending side wall member I8v of the strip framing. To produce such aframing, a flat rectangular strip oi metal, preferably of lightmaterial, such as aluminum, and comparatively thin, may be bent alongits longitudinal axis to the desired angu- A 90 bend will be sucient tot most conventionalvwindow frames, and probably some slightly less angleWillbe desirable to accommodate window frames which are built withsloping or slanting sides. Such a slanted condition in the window frameis commonly met on *that the mounted framing may presenta vertical wallI8 for mounting the screening thereon.

,The hooks I3, herein shown as pointed, rectan'gular projections,although *other suitable vshapes such as triangular may be desirable aswell, may be stamped or pressed out of the vertical wall member I8 ofthe strip framing at convenient intervals for fastening the screening I4thereto. As hereindisplayed, the hooks are 1A to 1 inch is suiiicient toevenly hold and ten-y sion most screening.

In addition to the base plate I1 and side wall I8, the framing II may beoptionally provided with a cover plate 20 for giving a finished outsideappearance to the framing and for preventing inadvertent unhooking ofthe screening I4...

from the holding hooks I3. The cover plate may .be formed out of thesame or similar material "as the vother framing members, beingessentially a fiat, rectangular strip of material bent at any angleAalong one margin to form a narrow lip l2I which isl adapted to lie in aparallel relation with the upper margin of the side wall I8, as shown inFigures 3 and 4, and provided for the purpose-of grippingthe screenbetween the lip and the side wall.

Suitable hinges 22, 22 may be mounted along the lateral marginal portionof the cover plate 20 opposite the lip margin `2I to provide connective'means between the coverplate and the base plate. As herein shown, thehinges 22 may comprise rectangular extensions of the `base and coverfplates, rolled into semi-cylindrical shape and interconnected forhinging movement by `a wire pin or rod ,'23, such being Va conventionalhinge construction commonly employed in sheet metal work.

As seen in Figures 3 and 4, the cover plate 20' fwill form thehypotenuse of a triangle formed by the cover plate, base plate, and sidewall when in a closed condition. Suitable fastening means may beprovided ,for securingthecover plate in its closed condition against thescreening jI4 and 'side wall II. YAs herein shown, the fastening Imeanscomprises va plurality of key-shaped fasteners ,25 which may be stampedout of the base plate 1I 'I to project upwardly therefrom throughreceiving slottedopenings 26 formed in registerlling position with thefasteners Yin the cover .plate '420, as clearly shown in Figure 2. YOther suitable 'fasteners *may obviously be used, but this ltype'affords the minimum productive expense and great simplicity ofoperation, as will be clear 'from jthe following description of theinstallation of this new'type of window screen.

Inorder to install a screen of `the type described above, it is merelynecessary to cut 'the strip framing III into'the desired lengths `to iitthe lwindow frames; cutting top, `^bottom and side /strips and cuttingthe side walls ata suitable mitre v29 'to nprovide-for a'tightttingcorner joint. -When ascover plate 20 is provided -withithe framf ing, itwill also be necessary 'to -cut back vthe corners of the -cover plate ata suitable mitre, such as is'shown in Figure2 at v31.), so that there iskno interference between the covers .at the-corners .of the completedframe. An ordinary tin snips or hack saw may be used to cut the framing.Having cut the frame strips to the desired length and 'beveled thecorners of the cover plates, the framing may then ybe mounted to thewindow frame either insideor outside ofthe window, as desired, bymeansof the screws I6.v With the frame thusly assembled around thewindow, a sheet of screening may but cut to the necessary length andstretched across the framing II, and held in place by means of the hooksI3. Insertion of the hooks about one-half an inch from the outsideborder of the screening will prevent unraveling of the screening. Thecover plates 20 may then be closed with the fasteners 25 projecting`upwardly through the registering openings 26. By turning the heads ofthe fasteners slightly to the right or left, so that the heads no longerregister with the slitted openings 26, the cover plate will be securelyfastened down, as shown in Figure 3. When it is desired to store thescreens, `itis merely necessary to unfasten the cover plates and removethe screening I4 from the hooks. The framing may be left on the windowframe and the screen rolled up for storage.

It is thusly seen thata window screen is hereby provided which is easilyinstalled, and capable of being readily removed and stored away in thewinter in the form of a frameless roll, which is light, takes littlestorage space and is easily handled.

While I have herein shown and kdescribed one form in which thisinvention may appear, it will be readily understood that numerouschanges, modifications and the use of equivalents may be used withoutdeparting from the spirit and scope of Vthis invention, and, therefore,I do not wish to be limited to the specic embodiments hereinillustrated, vexcept as may appear in the following appended claims.
